    2 Assumptions for each one..

    Radioisotope: (1) half life has remained unchanged and (2) radioisotope is same age as whatever is being dated

    Radiocarbon: (1) Levels of carbon-14 in atmosphere has remained unchanged and (2) ???

    Need another one for radiocarbon

    Any help would be much appreciated, thanks

    how about their easy availability and that further biofuel research needs to be done.
    Also use of biofuels can result in higher food prices and hunger.
